Atmospheric Absorption Loss Estimation of Terahertz-Wave Band Satellite Ground Detection

In satellite-borne Terahertz wave ground detection situation, the quantitative estimation of Terahertz wave atmospheric absorption attenuation loss, especially with designated satellite position and down-looking angle information, has always been fundamental and a key technology application for various Terahertz communication modes, such as wideband & high-speed network, interstellar communication, satellite-ground station link, stratosphere aero-craft communication, long distance vast data transfer, short range wireless security communication etc. This paper designed an atmospheric absorption loss estimation software on satellite global THz wave ground detection. The realized functions of this software including scene establishment, basic functions and calculation methods were explained in detail. Finally, the monthly change calculation results of satellite ground detection with 0.34THz working band in 10°–90° down-looking angle are given.
